This invention relates to improvemcnts in dispensing apparatus and is particularly directed to a cap and spout combination adapted to be applied to a receptacle. `he cap has an air conduit partially circumscribing the base of the spout and forming with the cap a channel communicating at one end with the interior of the cap and at the ot-herend directly with the atmosphere. The s'egmental arrangement provides a structure wherein the :inner orifice is adaptedto be disposed at a higher level than the outer when liquid is being dispensed through the spout.

The device is particularly designed for use with oil dispensing bottles, and is designed for handling lubricants which are for sale, and which are poured directly from the bottle into the Crank case or lubricant recepta'cle of an automobile.

The general object of the invention is to provide a cap which is attachable to a dispensing bottle, and which provides a spout through which the bottle can be filled, and further provides means whereby the rate of discharge may be Controlled by capping the intake end of the air 'conduit'above mentioned.

Another object of the invention is to so arrange the vent or air intake conduit that when the spout is in pouring position and when during pouring, little if any oil will be discharged into the vent, nor will the oil act to close the vent and prevent proper emptying of the receptacle. Another object of the invent-ion is to arrange the air orifices of the device in such la way that when the hand grips the receptacle, and when the inner orifice is disposed at the highest possible point the outer is disposed to be 'capped by 40 the fore-finger of the same hand which holds the bottle, all while the finger lies fiatly against the outer face of the cap substantially cangentially to the base of the spout, and lagainst the base of the spout to assist in gripping.

Features of the invention include the arrangement'on a bottle having a diameter easily gripped by the hand. Other features relate to the detailedV construction of the cap and conduit therein.

Other objects, features andcertain advantages of the invention will be pointed out in the description of the drawings forming a part of this application, and in said drawings Figure 1 is a top view;

Figure 2 is a bottom view;

Numeral 1 designates a bottle of the type shownin my copending application for oil Vending bottles filed January 22nd', 1926, Serial Number 83,015. The bottle per se forms no part of the present invention except in such a combination as will allow the bottle to be securely held by the thumb, and fingers, while the fore-finger lies .flatly against the outer surface of the cap, is position to engage and close or open the intake orifice of the air conduit of the cap. p

The bottle provides a reduced upper body portion indicated at 2 which is of a diameter easily grippable by the' hand. A circfumferential depression 3 is provided into which the 'thumb and second finger may lie while the 'cap has an air conduit extending therearound of arcuate configuration, in this instance eX- tending through an are of about ninety degrees. This conduit communicates at opposite ends respectively with the outer and inner cine" sides of the cap. Atmospheric air enters at 9, passes through the conduit and is delivered at the inner side of the cap through orifice 10, and therefore interiorly of the bottle when the cap is connected thereto. A protective lip 12 is provided on that side of the orifice 10 which is uppermost when the device is in pouring position, this for the purpose of preventing entry of liquid which flows down the sides of the receptacle, after the receptacle is partially emptied. c V

As herein shown the conduit is part of a shallow substantially Vcircular segment of sheet metal ancl is formed as a substantially semi-tubular section 11, in this instance, soldered to the outside of the cap to form the air conduit. This section 11 has an opening therethrough forming the inlet 9 for air, and the cap has an opening 10 spaced from the opening 9 and communicating with the conduit formed by the element 11, to deliver the incoming air into the receptacle.

The inner and outer orifices 10 and 9 are so arranged that when the spout is in pouring position the inner orifice is disposed at a higher level than the outer.

Moreover the arrangement is such that the outer orifice 9 can be capped by the fore-finger of that hand which grips the receptacle while that finger lies flatly against the outer face of the cap. "Furrtherinore, when the finger is in position to control the outer orifice, said finger lies substantially tangentially with respect to the spout in the angle between the spout and the cap, and thus a firin grip may be had also at that pointl to steady the device while pour- The advantages of'the construction are that the inner end of the air conduit or vent is disposed at such a level that the oil in fiowing out of the bottle will not interfere with delivery of air within thel bottle, and moreover oil will enter this opening. Furthermore the outer orifice is so arranged that when the bottle is in pouring position and when the finger is disposed to control it the inner orifice will always be positioned at ahigher level.

Another advantage of the construction.

shown herein is that the device can be closely nested as shown inFigure 5. rlChis has a great advantage over certain old forms in which the vent tubeprojects either from one or both Vsides of the cap. Thus in nesting the length added for each nested device is only substantially equal to the distance measured from the base of the spout to the base or end of the rim by which the deviceis attached to the bottle.

I olaim as my invention: 1. A cap having a spout and' a flat segmental channel element secured against the cap to form therewith an air passage, said cap and channel element each having an opening,

p said openings spaced apart and arranged respectively to admit air to the'passage and to permit delivery of air from the passage to the interior of the cap, the arrangement being such that when the device is in use the opening communicating with the interior of the cap lies at a higher level than that which admits atmospheric air to the channel, and a lip arranged to prevent entry of liquid fiowing on the inner side of the cap intovthat orifice which establishes communication between the interior of the cap and the air Chamber.

2. A cap and a spout therefor and a segmentalelement disposed adjacent the base of the spout and connected with the cap and forming therewith a channel substantially flattened in a direction aXially of the spout,

the channel element and spout being formedv to communicate at points. spaeed apart respectively with the atmosphere and with the interior of the cap, said element being curved in a plane perpendicular to the spout axis and extending substantially through an arc of ninety degrees with the points of communication substantially at opposite extrem'ities of the element, the arrangement being such that when the vfinger is positioned to control eni trance of atmospheric air it lies in the meeting angle of the spout capcand hollow element.

ln witness whereof, have hereunto set my hand this 10th day of March, 1927.
